SPECIFICATION forming part of Letters Patent No. 616,524, dated December27, 1898.

'Application tiled April 21, 1898. Serial No. 678,376. (No specimens.)

To a/ZZ whom it may concern.-

Be it known that I, WRIGHT R. CARTLEDGE, manufacturer, of the city ofToronto, in the county of York, in the Province of Ontario, Canada, haveinvented certain new and useful Improvements in Bandage Fabrics, ofwhich the following is a specification.

My invention relates to improvements in bandages for abdominal and otherpurposes; and the object of the invention is to devise a fabric forbandages of this class which will not turn up or curl at the outer edgesthereof, but will conform closely to the gure or other portion of thebody designed to be covered, and thereby maintain an even pressurethroughout its width; and it consists, essentially, of a knitted fabriccomprising a number ot courses looped together and having a supplementalcourse knitted between the ordinary regular courses and having placedlongitudinally therein an elastic thread or cord which is knitted intothe fabric from the bottom to the top edge in a continuous thread orcord, the fabric being otherwise arranged so as to leave a smoothportion next the body and the ribs to the outside, as hereinat'ter moreparticularly explained.

Figure l is a perspective view show-ing the general appearance of anabdominal bandage constructed in accordance with my invention. Fig. f2is an exaggerated view of aportion of the fabric, showing the variouscourses of stitches and the supplemental stitches with continuouselastic threads placed therein, the threads being drawn apart to exhibitthe peculiar manner of knitting the courses. Fig.

is a similar view to Fig. 2, showing an alternative form of knitting thecourses. Fig. 4 is a section either through Fig. 2 or Fig. 3.

ln the drawings like letters and numerals of reference indicatecorresponding parts in each figure.

A is the thread or yarn, of which a is the lower course or series ofloops.

B is the elastic thread or cord, which passes through the lower or edgeportions of the loops iirst under one loop and over the adjacent loopalternately, as indicated. The course of loops a are on the edge ofequal length. The next course of loops a are alternately of unequallength, and the continuous elastic thread B is looped at the end andpasses alternately behind one loop and in front of the other from end toend of the fabric. The

next course (marked a2) passes from the end 5 5 marked l insubstantially V-shaped loops and ordin ary loops alternately through theshorter loops of the course marked a'. The end marked 2 of the course aspasses up into the course a3, which consists of a series of loops 6o ofequal length. The course ot the loops a3 passes through the ordinaryloops and V- shaped loops of the course a, and the alternate loops ofthe course a3 pass through the elongated alternate loops of the course aat the same point as they p ass through the V- shaped alternate loops ofthe course a2.

It will be noticed that the continuous elastic thread or cord is loopedat the end 3 and passes through under the elongated loops of 7o thecourse a and the V-shaped alternate loops of the course a2 and over theordinary loops of the course a2. It will thus be seen that thecontinuous elastic thread or cord is completely incased, and especiallywill this be understood when it is comprehended that all the courses lieclose together, as shown in the drawings, the V-shaped loops beingpractically parallel with the rest of the loops.

This form so far described is for the outer 8o edge of the bandage andmaybe repeated into as many rows or courses as may be desired.

In the interior portion I preferably provide the continuous elasticthread with looped'85 in alternation with the ordinary loops, are

knit through the loops of the course at. The inner end of the V-shapedloop portion of the course extends to the end of the loops of the coursed5. The course a, following, as to the loops thereof, are of equallength and half roo pass through the elongated loops of the course a4,as well as the apexes of the V-shaped loops It will there- 9oalternately. The other half of the loops pass through the ordinary loopsof the course d5. The end 4 of the continuous elastic thread or cordpasses through under the elongated loops of the course CL4 and theV-shaped loops of the course a5, but over the ordinary loops of thecourse a5, thus completely incasing such elastic cord or thread, so thatwhen the courses are of the exact size no such thread appears exceptwhen stretched, and this is just exactly similar to the passage of theelastic cord or thread, hereinbefore described, as to the formerV-shaped loops and the corresponding loops of the course. At the end 5the elastic thread or cord is turned again and passes two sets of loopssimilarly formed t-o the loops of the courses a4 and a5, and this formwill be maintained until the opposite edge of the bandage is reached,when it is formed, as hereinhefore described,. corresponding to theloops of the courses ct a' and 0.2 and d3.

I have only shown three sets of courses of "loops on the edge; but itwill of course be understood that there may be as many rows of coursesas may be desired to give the requisite strength and prevent curling up.Under ordinary circumstances I find that ten courses make the materialat the edges sufficiently wide to produce the desired effect.

In the manner in which I have described my knitted fabric with itselastic thread it will be noticed on reference to Fig. 4 that the endsof the loops will be presented on the lefthand side of Fig. 4, while thesmooth portion, which will be next the body, Will be on the oppositeside, as indicated in this figure, thus making the side next the bodysofter, and thus more comfortable.

In Fig. 3 I show an alternative form in which the supplemental courses,which I term V- shaped, are arranged somewhat differentlywill have thesides of the loops parallel to each other.

That I claim as my invention is- A bandage fabric comprising a pluralityof series of courses, each series having the first course thereofcomposed of a series of loops of equal size, the second course composedof short and lon gloops alternately arranged, the third course composedof oval and V-shaped loops alternately disposed, and the first course ofthe second series composed of loops of equal length, said loopsalternately passing through the oval loops of the said third course andthrough both the elongated loops of the second and the V-shaped loops ofsaid third course and the elastic cord passed alternately over and underthe loops of the iirst course and then doubled and passed alternatelyover and under the loops of the second course and doubled again andpassed over the oval loops of the third course and under the V-shapedloops of said course and the long loops of the second course and doubledaround the first course of the second series and passed between theloops of the third course of said second series, substantially asdescribed.
